The actor's characters were well portrayed and executed as Do really gave me the impression of a loving husband and father but later on if he was accused of killing someone I wouldn't be too surprised. Ji-Won was excellent in showing she is independent so isn't an accessory and the young cop who gets pulled in two directions.
The story was intriguing it kept me glued in wondering what was going to happen next. The flashbacks were embedded at the right time as they aid in further understanding the characters.
The romance between the sister and reporter I skipped as it felt awkward and forced as they had a history together yet he wonders how she ended up killing the head.
